Router issues can cause problems with the internet. If your internet is as slow when your smartphone or other device is connected to Wi-Fi, chances are, the trouble is not with your Mac. To fix the slow connection, try restarting your router. Simply turn it off, wait a few seconds and turn it on again.
You can also try to relocate your router, so it’s closer to the place where you usually connect. Make sure no objects will affect the signal, like microwaves and various metal things.

While the wireless internet is more convenient, connecting directly to the router with a cable provides the faster connection. Many people don’t realize that and still use Wi-Fi even if they are close enough to the router to use the cable. In fact, Wi-Fi rarely achieves the speed that Ethernet can due to the signal loss, distance from the router, and many more. The best solution is to simply plug your Mac in using a cable and you’ll notice the considerable speed boost.

Update The macOS

Close Unnecessary Apps And Browser Tabs

Internet running slow on Mac? If you have dozens of apps and websites open, such as Skype, Safari, Mail, Facebook, Twitter, and many more, then they are all trying to connect to the internet from time to time to update and synchronize. It makes the Mac internet slow and the websites start to hang. That’s why close unnecessary apps and tabs in your browser. Believe us, your Mac will thank you for that!

Remove Existing Wi-Fi preferences

Switch To Another Web Browser
